Public bug reported:

This commit added some new default flags for migration in the libvirt
driver:

https://github.com/openstack/nova/commit/26504d71ceaecf22f135d8321769db801290c405

However those new flags weren't added to
nova.tests.virt.libvirt.fakelibvirt, so if you're not running with a
real libvirt you're going to get this:

That is in basically anything that goes through the _live_migrate
method.
